Selection Guide
Start with the conductor section and corresponding color group. Match the ring hole diameter and tongue width to the screw or stud, then check clearance and clamping requirements. Use crimp tooling suitable for the terminal and conductor, then apply heat according to the approved installation instructions. Send the mating-part reference or assembly drawing for selection assistance.
Applications
Compatible stud connections in control wiring, equipment assemblies and wiring-harness maintenance. Confirm the mating hardware, conductor, operating conditions and connection requirements for the exact model and finished assembly.
Ordering Information
Provide the full RSRV model reference, conductor size and mating-part dimensions, order quantity and intended application. Include packaging, labeling and delivery requirements for OEM and wholesale enquiries.
